Trays

Trays

(OP)
What are the typical NDE testings done by tray fabricator before shipping off the tray unit to the job site?

RE: Trays

This question is more applicable to chemical process design and operations if you mean distillation trays..

Waht do you mean by NDE,,

As a minimum they should best the tray fits together correctly and can be assessmebled internally in the dimeter column that you are working within.

RE: Trays

(OP)
NDE stands for non-destructive testing such as radiographic examination, ultrasonic testing, mag particle testing etc. these tests are common in vessel fabrication, but what about tray fabrication? I will try to post my Q in some other more applicable forum.

RE: Trays

Positive Material Identification (PMI) is probably about the closest thing to NDT (testing) or NDE (examination) you'll see done to trays.  Trays that require welded fabrication my have liquid-penetrant inspection.

Quality assurance & control (QA/QC) measures are more applicable to trays than NDT/NDE.
